Configuring AD authentication
Active Directory (AD) is a directory service provided by Windows 2000 Server and later versions. It
saves information of objects on a network and allows administrators and users to query the information.
AD uses structured data storage, which is the basis of the directory information logical structure. The SSL
VPN system can cooperate with the existing AD server of an enterprise seamlessly to provide AD
authentication for users in the enterprise.
For successful AD authentication of a user, you must also configure the user information on the AD
authentication server, create user groups, and add the user to the user groups. Make sure the user groups
configured on the authentication server exist on the SSL VPN gateway. Otherwise, the user cannot log in.
The number of user groups that the gateway supports for a user has a limit. Make sure the number of user
groups specified for a user on the authentication server is equal to or less than the limit.
1. Select VPN > SSL VPN > Domain Management > Authentication Policy from the navigation tree.
2. Click the AD Authentication tab. The LDAP authentication configuration page appears.
